noise with dust control

[bandaideman]

Back ground; I have a Dewalt 788 and probably 20 years ago I ran across a dust collection system made specifically for the Dewalt. It was made by a gentleman in Indiana where I lived at the time. It was patented etc. I have had it installed on my scroll saw for the 20 years and it is wonderful. So I decided when I added the Ex 20 to my shop I could do the same with it.  Problem is the man who developed the one I have I do not think is made any more it was a very local market and the gentleman has since passed away some time in the 20 years. I decided I could make one for the Ex I the same style and have done pretty good. Now the problem the hose I used is a sump pump hose 1 1/2 or 1 1/4 inch. All went well and have the hose doing the bottom and top and looked good just like the other. The difference is the Dewalt designed one uses vacuum hose same size and had a narrower nozzle top and bottom with a 1/2-3/4 inch opening. I can not find these nozzles. The are snap segments like the blower tube but bigger. Thought would be OK with the open end of the hose positioned to clear the top and bottom. Well turn on dust collector and it sounds like an Elk in the wild who was just rejected by two of the lady Elk at breeding time. That is loud if your right next to the saw or even in the house.  Any thoughts please let me know. I am not real Mechanical or engineer like man but think could it be the hose opening is too big and I need to find a way to narrow it. Thank you for your help. Sorry so long.

Without pictures I don't believe what you are describing exists.

ROFL

On a biker community I haunt, we tell folks take the pic with a broom, no broom it must be photoshopped {grin}

Sorry I knew pictures needed but I do not do well posting photos and until now have never been able to. I did have 2 pics and could only do one but that is a start. I will see if I get more photos including the EX I will try putting more up. right now I am just winging it. Keven thanks for the link. I will see what I can find. cross your fingers that I can figure out how I posted this one.

Thanks for the pics. That was a pretty neat setup. What you are looking for is the Loc-line products and here is their link.

I am posting for practice. This is the results of the ex 21 with out the Loc-Line. It is nice to know I can share pics now that I have a system.

you are looking for loc line.  3/4" loc line interfaces with a 3/4" pvc threaded connector.

the elk sound is because of something whistling.  you will need to look for leaks, make sure nothing can buzz (all piping is fastened securely), and you may need to play with the shape of your dust pickup end.  I built my dust collector using the loc line and have no whistles.

The whistling could be too that a line is blocked or partially plugged.  Just thought of that.

thank you Matthew. I am in the process of ordering the Loc line and will let you know if that quiets it down everything seems tight but will run the tubing for leaks. since hooking the one from the Dewalt to the Ex results in no noise and vice versa the opening needs narrowing. thanks for the link
